 I don't know how Mike did it. The soles have kind of a memory foam and the MyPillow material. They're two styles, slip-on and moccasin. They come in men's and women's, all different sizes. You go to MyPillow.com, go to that Mike Gallagher Radio Square, and then when you put your order in, you enter the promo code MikeG, you'll save 50% off the MySlippers.
